About the Client

A state government agency undertaking a major land governance modernization program as part of the National GIS initiative. The objective was to create a high-accuracy digital land base to support interdepartmental coordination, transparent decision-making, and citizen-facing e-governance platforms.

The Challenge

The client lacked a centralized, standardized, and high-resolution geospatial database to support effective planning and land management. Departments operated with siloed data sources, leading to data duplication, inefficiencies, and limited accessibility.

Key challenges included:

• No single authoritative base map for statewide infrastructure and land use
• Inconsistent or outdated records across departments
• Difficulty accessing spatial data due to physical file handling and lack of digital sharing mechanisms
• Need for high-precision mapping to support future planning, dispute resolution, and development

The Solution

We developed a robust Spatial Data Infrastructure (SDI) based on high-resolution (50 cm) ortho-rectified satellite imagery. The solution focused on multi-theme feature extraction, base map generation, and creation of an integrated geo-portal.

Key solution components included:

• Procurement and use of 50 cm ortho-corrected satellite imagery
• Feature extraction at 1:2,000 scale across Urban, Transport, and Water themes
• Creation of a centralized land use/land cover mask incorporating Forest, Wasteland, and Agriculture layers
• Development of standardized GIS data models with exhaustive attribute schema
• Centralized geo-portal hosting a Decision Support System (DSS) with department-level custom views
• Web-based data access to minimize redundancy and physical data transfer
• Creation of a government asset inventory layer for public works, water resources, and planning departments

The Impact

The SDI solution significantly improved transparency, accessibility, and decision-making capacity across state departments:

• Centralized digital repository for land records, base maps, and asset inventories
• Enabled interoperability between departments like Irrigation, PWD, and Urban Planning
• Reduced data duplication and eliminated reliance on physical data sharing
• Created the foundation for e-governance and public-facing land record systems
• Supported dispute resolution and project planning through accurate, accessible spatial data

Key Project Highlights

• Mapped 307,713 sq. km using high-resolution satellite imagery
• Feature extraction and interpretation at 1:2K scale
• Reduced data duplication and eliminated reliance on physical data sharing
• 4 thematic base layers: Transport, Water, Urban, and Land Use Mask
• Integrated GDB structure with coordinated feature class relationships
• Scalable architecture aligned with National GIS and SDI standards
